2 Claims.

My invention relates to packages, and more particularly to an improvedpackage, to an im-. proved covering for packages, and to the improvedmethod of applying such covering.

ticles made of distortable material having an inner and outer diameter,the outer diameter being the greater, as in articles having a toroidalform, particularly tire shoes or casings.

.1) Prior to the shipment of tire casings from the factory, the same areenveloped in a covering of wrapping material. This is done for aplurality of reasons, such as the protection of the tire casing frominjury, the maintaining of the tire 5 casing in new or fresh condition,and the labelling of the different sizes and grades of tire casings inorder that they may be readily identified. Because of the toroidal shapeand distortable qualities of a tire casing, and because of 20 theconsiderable total displacement thereof, it

has been found difficult to satisfactorily and cheaply envelope the samein a wrapping material possessed of the requisite rigidity and wearresisting qualities, and in a form that will suecessfully resist thesevere shocks to which the same are subjected before reaching theultimate consumer.

It has heretofore been proposed to use as an enveloping material a softpaper, such as crepe paper, but the very nature of this paper renders itsusceptible to deformation and injury, and in the main, has been foundunsatisfactory. The form of the wrapper has been varied from time totime, until at present the accepted form is the so-called wrap aroundwhere a relatively narrow strip of paper is helically wound around thesubstantially circular cross section of the tire casing. A wrap aroundenvelope of crepe paper is subject to all the objections pointed outabove, and has been found to be unsatisfactory.

5 fault.

51) cause of the character of the material of the enveloping material,it is inelastic and inextensible, and consequently, when subjected toshock, as by dropping the tire casing from a height, or suddenlydeforming the tire casing, the enveloping material splits and isdestroyed. In spite of these defects the wrap around envelope of manilaor like papers appears to have become standard in the tire trade.

In my present invention, I have overcome the 60 defects in priorwrapping devices, and have pro- 'duced an enveloping wrapper for tirecasings and the like in which all of the advantages ofboth crepe andmanila paper are embodied, and in which, because of the form of theenvelope, none of the defects of prior devices are present.

. In carrying out my invention, I utilize a strip or band of. a strong,relatively smooth, flexible material, such as manila paper, or acomposite paper comprised of a layer of paper on one face of which isspread a layer of waterproofing material, such as asphaltum, the exposedface of the asphaltum being covered with an open netlike material, thestrip extending about the outer periphery of the tire casing and lyingsmoothly in engagement therewith without distortion. The strip ofenveloping material is wide enough to fold over and protect the sidewalls of the tire casing and to infold into the interior thereofsufficiently to protect said interior and any article that may be placedtherein, as a tube and/or a tube protecting strip. To conform thelateral portions of the encircling and enveloping strip of paper to thecontour of the side walls of the tire casing and to infold or tuck theedges of such lateral portions to a position within the tire casing, Ifold, or pleat the material thereof on radial or substantially radiallines, with respect to the tire casing and transverse to the length ofthe strip. Such folding or pleating not only and folds and/or pleats thepaper simultaneously with the application of the strip to the tirecasing.

The absence of the enveloping material across the inner diameter of thetire casing, or from one bead portion to the other, removes thepossibility of a breaking strain being placed on the envelopingmaterial, and thus removes the most frequent cause of rupture of suchmaterial. I am aware'that it has been proposed to infold crepe paperenveloping material to a point within the tire casing, but the nature ofsuch paper precludes its remaining in set position. But in no instanceof which I am aware has it been found practical to utilize a stiffmanila, kraft, composite board, or similar paper in this situation.

The principal object of my invention there- Another object of myinvention is an improved package.

Another object of my invention is an improved covering wrapper for tirecasings and the like, in the form of stiff sheet material partiallyenclosing a tire casing.

Still another object of my invention is an improved covering wrapper fortire casings having the form of an encircling band of stiff materialhaving the lateral edges housed within the interior of the casing.

A further object is an improved method of applying an enclosing envelopeto tire casings.

Other objects and novel features of the construction and arrangement ofparts comprising the wrapper and the methods of applying the same willappear as the description of the invention progresses.

Referring to the drawings, l0 designates a strip of wrapping material,of smooth, flexible and substantially inextensible sheet material, suchas manila paper, kraft paper, composite board, or other like suitablematerial, of any suitable width and preferably of indeterminate length.When of indeterminate length the strip may be conveniently furnished inrolls, large or small, as desired, and cut off in lengths equal to thecircumference of the tire casing to be wrapped, or enough longer toprovide for a sufficient overlap. If preferred the strips may have theirends joined prior to the folding and pleating operation. The form inwhich the strip of wrapping material is furnished therefore, isimmaterial as far as concerns the novelty of my invention, and in thesubsequent description of my invention it will be assumed that the stripID of wrapping material is of indeterminate length.

The reference numeral ll designates in its entirety a distortablearticle of toroidal shape, such as a tire casing of the usual straightsided type having a tread portion i2, the sides l3, and the beads H, thetread l2 defining the outer diameter of an annulus, and the beads I4 theinner diameter.

The strip III of wrapping material is wrapped around the circumferenceof the tire casing ll,

the medial longitudinal portion l5 of the strip engaging with the treadl2 and lying smoothly thereon. The ends of the strip Ill overlap, as atIt, and the overlapping ends are secured together, preferably bysuitable adhesive. The lateral portions I! of'the strip III are dividedinto three zones I8, l9 and 20, the zone I9 being defined by theparallelly arranged dash lines 2 l, 22. The lateral portions H areprovided with parallelly spaced dash lines 23 perpendicular to thelength of the strip l0. Also the lateral portions I! are provided withparallelly spaced dash lines 24 extending at an angle to the length ofthe strip Hi. The dash lines 23 and 24 are arranged in pairs, as shownin Fig. 6, and the lines of each pair meet at the edge of the mediallongitudinal portion ii of the strip Ill. The dash lines 23 and 24 formlines of fold for the lateral portions I! of the strip III, the dashline 23 designating an outside fold, and the dash line 24 designating aninside fold, as will be obvious from an inspection of Figs. 1, 3, and 5.

The strip III has been described as having the dash line 2|, 22, 23, 24etc. on its surface, but such need not be, and preferably is not,actually the case. The various lines designate lines of folding orpleating, and the actual folding or pleating make lines or creases inthe body of the strip III. In the completed enveloping wrapper, when atire casing is actually enveloped therein, such lines or creases arequite apparent. The dash lines referred to therefore, may be consideredas being referred to as a matter of convenience to more clearly setforth applicants invention.

In addition to the dash lines above referred to, there .is shown, inFig. 6, other dash lines 25 running from an end of the dash lines 23 toa point intermediate the ends of the dash lines 24. This designates theline of fold or crease taken by the material of the outer edge of thezone 20 when such zone is inserted within the tire casing l I betweenthe beads l4.

As stated above, the folding of the lateral por tions l'l takes placesimultaneously with the placing of the strip II] on the tire casing ll,so that the folding on the lines 2-3 and 24 progresses simultaneouslywith the placing of the strip ii], and is completed when the overlap I6is reached.

The enclosing envelope now has the appearance shown in Fig. 3. The nextstep is the folding inwardly of the shaded portion in the centre of Fig.3, or the beginning of the formation of the zone IS. The Zone i9 is nowin engagement with the top of the bead l4, whereupon the zone 20 isfolded to a position within the tire casing II, this operation beingfacilitated by the presence of the lines of fold 25. When within thetire casing ii the edge portion of the zone 20 of the strip l0 expandsto practioally its original size and thus acts as a means for lockingthe strip ID in enveloping position on the tire casing H, holding thesame firmly in position.

The folding, creasing and infolding of the strip l0 may be done manuallyor by mechanical means. It is contemplated that such operations will beperformed by machinery, but the method is not limited to such machinery,nor is the product limited to one capable of machine use only. Themethod of folding and pleating to obtain an enveloping wrapper accordingto my invention may be varied to suit different tastes or requirements.One method of folding a pleating is described above in connection withthe appropriate figures of the drawings. v In Figs. 7,8, and 9, I haveillustrated another method of practising my invention. Referring to suchFigs. 7, 8, and 9, where in Fig. '7 shows a strip 33 completelyenveloping a tire casing, Fig. 8 a portion of a strip 30, partly insection, and in position on a tire casing, and Fig. 9 a developed viewof a portion of a strip 33 of wrapping material, it 'will be noted thatthe appearance of the strip 33 in tire casing enclosing condition isdistinctly different from the similar condition of the strip III in Fig.1 for example.

The strip 30 of wrapping material is provided with a medial longitudinalzone 3| and lateral portions 32, as in the strip Ill. The lateralportions II are divided into three zones 33, 34. and 35. The lateralportions 32 are defined by parallelly arranged dash lines 33. Thelateral portions 32 are also provided with parallelly spaced dash lines31 perpendicular to the length of the strip 30, and with pairs of dashlines 33 and 33 extending from the inner ends of pairs of dash lines 31to a point at the outer edge of the strip 33 midway of the outer 'endsof such dash lines 31. The dash lines 33 and 39 are arranged at an angleto the length of the strip 33; Further, the dash lines 33 are parallelto each other, and the dash lines 39 are parallel to each other. Inaddition to the above, the strip 30 is provided with dash lines 43extending from a point intermediate theends of the dash lines 33 and 39to the outer ends of such lines.

As in the showing in Fig. 6, the dash lines in Fig. 9 may be actuallyimpressed on or in the strip 33.- Preferably however, no lines of anycharacter are on the strip 30, such lines as have been described beingmade in the strip preferably during the operation of folding, pleatingor creasing the material to conform the same to a tire casing. Suchlines as have been described therefore designate the lines of folding orpleating. The dash lines 31 designate outside folds or pleats; the lines33 and 2! inside folds or pleats; and the lines 40 expansion folds orpleats. V

Preferably, as the strip 30 is being applied to the tread l2 of the tirecasing H, the outside folds or pleats 31 and the inside folds or pleats33 and 33 are formed to thereby conform the lateral portions 32 to theside wallsl3 of the tire casing ll. Subsequently the zone 33 is broughtinto engagement with the face of the bead H of the tire casing ll, afterwhich the zone 35 is infolded to a position within the tirecasing I I.

The result is as shown in Fig. '7, where the space between pairs of dashlines 33 extend radially, or substantially radially, of the tire casingII. The inherent stiffness of the material of which the strip 30 iscomposed, combined with the fact that' a closed'band of suitableperimeter and width,

and with the folds or pleats physically formed in the material thereof.Both the perimeter and width of the closed band will naturally vary inaccordance with the outer diameter and size of the toroidal article tobe wrapped, and such band may or may not have the folds or pleatsphysically preferred.

formed in the material thereof prior' to the application of the band toa tire casing.

In the form of a band, my improved wrapper is particularly adapted formanual application to a tire casing, and as such, is within the scope ofmy invention.

"The method of feeding the strip'of material relative to and applyingthe same to the tire casing, or other toroidal object may be carried outas For example, the strip material may be fed from a roll to the tirecasing or other toroidal object and passed about the same, or the tirecasing or other toroidal object may be rotated relative to the stripmaterial. The manner of folding, i. e. weakening the areas of the stripmaterial may be carried out-by forming the folds at the predeterminedareas of the strip material in advance of the application of the stripmaterial to and about the tire casing or other toroidal object or thestrip material may be brought into position relative to the tire casingor other toroidal object and the folds formed at the predetermined areasprogressively as the strip material is applied.

The infolding or tucking-in of the opposite edges of the strip materialis effected in any suitable manner.

The steps in the method of applying the strip material to the toroidalobject, such as the preweakening of the areas of the fold lines, theapplication of the strip material about the tread, or outer periphery ofthe toroidal object, then about side walls thereof, and the tucking-inand final locating of the infolded portions of the strip material may becarried ut manually or by means of suitable apparatus.

Objects other than tires and tire casings and of a general toroidalformation, either solid or hollow, are enwrapped in a manner similar tothat hereinabove described.

Various other methods of folding the strip l3 and 30 onto a tire casingwill readily suggest themselves to those skilled in the art; and I amnot to be limited to merely those illustrated and described.

I claim.

1. A wrapper for tires and the like comprising a strip of flexible sheetmaterial equal in length to the perimeter of the article to be wrapped,a medial zone extending along the length thereof being undisturbed andadapted to be placed in engagement with the tread of the tire, and thezones on either side of the medial zone having formed therein folds orpleats extending transversely of the length of the strip and conformingthe material of the said zones to the contour of the side walls of thetire, and additional folds or pleats formed in the side zones adjacentthe side edges of the strip, and adapted to conform the material of theedge portion of the strip to the surface of the interior of the walls ofthe tire adjacent to the bead portions thereof.

2. A package comprising a distortable article such as a tire casing, anda wrapping consisting of a strip of smooth, flexible. paper extendingcircumferentially of the tire casing in engagement with the treadportion thereof, and with the side portions of the strip folded orpleated and brought inwardly into conformity with the contour of theside walls of the tire casing-the edges of the strip being additionallyfolded and pleated and unfolded around the beads of the tire casing intothe interior thereof.
